The room is a class 10,000 clean room with over one million cubic feet of space.The outside half of Roman, called OSD, contains the solar panels and protective layers. The Deployable Aperture Cover, which protects the mirrors during launch and then unfolds to help shield them from sunlight does a test deployment. During this test, lines connect to it and pull upward to negate Earth’s gravitational forces, which Roman will not experience in space. Then the Solar Array Sun Shield panels deploy. There are four panels that move. They fold against the spacecraft to fit inside the rocket fairing and then deploy in space to make a large flat plane that both collects light to generate electricity and helps keep the rest of Roman cool.In preparation for additional testing, technicians put a clean tent over OSD and transport it out of the clean room. They push it into the acoustic test chamber where a six-foot-tall horn projects up to 150-decibel sound at varying frequencies. The other tests are on two vibration tables that shake Roman along all three axes: up/down, left/right, and forward/backward. Engineers attach hundreds of sensors and run tests of increasing intensity. During and after each test, they carefully study the data to make sure that Roman is behaving as they anticipated.While these tests occur, Roman’s inside half, containing the mirrors, instruments and support equipment, move into Goddard’s largest thermal vacuum chamber, the SES (Space Environment Simulator). This 40-foot-tall chamber can simulate the vacuum of space and the wide temperature range that Roman will experience there: from -310° Fahrenheit (-190° C) to 302° Fahrenheit (150° C). The move to the chamber happens without a clean tent, so the entire path was cleaned, and all the workers dress in full clean-room garb to ensure that no dirt contaminates the sensitive parts of the spacecraft. Once the two layers of doors are sealed, Roman spends 72 days inside running through tests at various temperatures and with equipment turned on to ensure that it works at low temperature in a vacuum. A special array installed above the mirror projects light that engineers use to test the optics and sensors.After leaving the SES chamber and returning to the SSDIF, Roman’s primary and secondary mirrors are carefully cleaned and inspected. It is a balance to get the mirrors as clean as possible while not cleaning too aggressively and damaging the delicate surfaces. The mirrors are cleaned both horizontally with a gentle vacuum cleaner and vertically with brushes. After this cleaning, every inch is visually inspected and photographed to record the exact optical characteristics. This was the last time the primary mirror would be accessible.Finally, in late November, Roman’s two halves are joined together to form the complete observatory. The process takes the better part of a day. Two guide poles are installed on the inside half to help direct OSD down onto it. At various times, the clearances between the two halves are only a few inches. With the observatory complete, it begins preparing for another round of deployments and testing.Music credit: “Our Journey Begins,” Dan Thiessen [BMI], Universal Production MusicWatch this video on the NASA Goddard YouTube channel.Complete transcript available. || YTframe_Roman_Hardware_Highlights_SummerFall2025_3.jpg (1280x720) [473.7 KB] || Roman_HH_Summer-Fall2025_10mbps.mp4 (1920x1080) [185.0 MB] || Roman_HH_Summer-Fall2025_25mbps.mp4 (1920x1080) [452.7 MB] || Roman_HH_Summer-Fall2025_YT.mp4 (1920x1080) [880.2 MB] || RomanHHLate2025Captions.en_US.srt [588 bytes] || RomanHHLate2025Captions.en_US.vtt [570 bytes] || Roman_HH_Summer-Fall2025_ProRes_1920x1080_2997.mov (1920x1080) [2.5 GB] || ", "hits": 271 }, { "id": 5149, "url": "https://svs.gsfc.nasa.gov/5149/", "result_type": "Visualization", "release_date": "2023-09-26T17:00:00-04:00", "title": "GEOS-FP Precipitation and Clouds", "description": "Precipitation and clouds are calculated using fields from NASA’s GEOS-FP system.

These traces provided an unexpected window into what low-emissions world could look like, thus providing a means for identifying effective environmental policies. While many countries in the last few decades have implemented environmental policies to reduce human health risk from air pollution by controlling emissions, the impacts of those policies have not always been clear. The global lockdowns in response to COVID-19 represent a well-observed “scenario-of-opportunity” that allows us to assess how atmospheric emission and composition responds to reduced human activity. COVID-19 lockdowns effectively showed how reducing NOx emissions affects the global atmosphere. Its identifying signature shows up as in the atmosphere’s altered ability to produce harmful ozone pollution and ozone’s reduced influence on Earth’s heat balance that affects climate. These effects are not uniform across the world and depend on the location and season of the emission reductions.The results of this research indicate that in order to design effective environmental policies which benefit both air quality and climate, decision-makers need to carefully consider the complex relationships between emissions and atmospheric composition. || ", "hits": 72 }, { "id": 4849, "url": "https://svs.gsfc.nasa.gov/4849/", "result_type": "Visualization", "release_date": "2021-04-19T09:30:00-04:00", "title": "Godzilla Dust Storm", "description": "Visualization of the Godzilla Dust Storm during June 2020. || GodzillaShot1_1920x1080_60fps_2222_print.jpg (1024x576) [259.0 KB] || GodzillaShot1_1920x1080_60fps_2222_searchweb.png (320x180) [117.7 KB] || GodzillaShot1_1920x1080_60fps_2222_thm.png (80x40) [8.7 KB] || GlobalView (1920x1080) [0 Item(s)] || GlobalView (1920x1080) [0 Item(s)] || GodzillaShot1_1920x1080_60fps_2222.tif (1920x1080) [10.2 MB] || GodzillaShot1_1920x1080p30.webm (1920x1080) [8.7 MB] || GodzillaShot1_1920x1080p30.mp4 (1920x1080) [115.7 MB] || GlobalView (3840x2160) [0 Item(s)] || GodzillaShot1_3840x2160_60fps_2222.tif (3840x2160) [38.1 MB] || GlobalView (3840x2160) [0 Item(s)] || GodzillaShot1_3840x2160p30.mp4 (3840x2160) [377.9 MB] || GodzillaShot1_3840x2160p60.mp4 (3840x2160) [425.4 MB] || GodzillaShot1_1920x1080p30.mp4.hwshow [192 bytes] || ", "hits": 234 }, { "id": 13646, "url": "https://svs.gsfc.nasa.gov/13646/", "result_type": "Produced Video", "release_date": "2020-06-19T00:00:00-04:00", "title": "NASA Satellites Help Farmers in Central America's Dry Corridor", "description": "Music: \"Beautiful Serenity,\" Samuel Karl Bohn & Anthony Phillips, Universal Production Music.Complete transcript available. || Elsalvador_thumb_print.jpg (1024x570) [271.1 KB] || Elsalvador_thumb_searchweb.png (320x180) [151.0 KB] || Elsalvador_thumb_thm.png (80x40) [11.9 KB] || ElSalvador_Twitter.mp4 (1920x1080) [43.5 MB] || ElSalvador_prores.mov (1920x1080) [2.7 GB] || ElSalvador_YouTube.mp4 (1920x1080) [325.4 MB] || ElSalvador_prores.webm (1920x1080) [27.3 MB] || elsalvador.en_US.srt [3.6 KB] || elsalvador.en_US.vtt [3.6 KB] || ", "hits": 21 }, { "id": 4782, "url": "https://svs.gsfc.nasa.gov/4782/", "result_type": "Visualization", "release_date": "2020-03-04T00:00:00-05:00", "title": "Vegetation Index Anomalies and Rift Valley fever (RVF) outbreaks in South Africa region: 2008-2011", "description": "This visualization with corresponding data dashboard shows the relationship between vegetation index anomalies and outbreaks of Rift Valley fever (RVF) during 2008 and 2011 in the South Africa region.

The above-normal rainfall is followed by an increase in vegetation creating appropriate habitats for the mosquito vectors setting the stage for RVF outbreak activity, which in simple terms means an uptick in mosquito populations that cause infections of domestic livestock and human populations with the RVF virus. However, in rare cases there is a departure from this canonical response, as we can observe in 2009-2010, when a mild El Niño event resulted in above normal vegetaton and a large RVF outbreak in South Africa. || ENSO_TeleconnectionsRVF_2008_2011_3840x2160_2960_print.jpg (1024x576) [107.8 KB] || ENSO_TeleconnectionsRVF_2008_2011_3840x2160_3525_searchweb.png (320x180) [63.0 KB] || ENSO_TeleconnectionsRVF_2008_2011_3840x2160_3525_thm.png (80x40) [6.5 KB] || ENSO_Teleconnections (1920x1080) [0 Item(s)] || SST_Precip_NDVI_Dashboard_2008_2011_1920x1080_p30.mp4 (1920x1080) [22.7 MB] || ENSO_Teleconnections (3840x2160) [0 Item(s)] || ENSO_Teleconnections (3840x2160) [0 Item(s)] || ENSO_TeleconnectionsRVF_2008_2011_3840x2160_p30.mp4 (3840x2160) [56.0 MB] || ENSO_TeleconnectionsRVF_2008_2011_3840x2160_p30.webm (3840x2160) [10.2 MB] || ENSO_TeleconnectionsRVF_2008_2011_3840x2160_2960.tif (3840x2160) [3.4 MB] || ENSO_TeleconnectionsRVF_2008_2011_3840x2160_3525.tif (3840x2160) [3.4 MB] || ", "hits": 56 }, { "id": 4754, "url": "https://svs.gsfc.nasa.gov/4754/", "result_type": "Visualization", "release_date": "2019-12-09T00:00:00-05:00", "title": "The Complex Chemistry of Surface Ozone Depicted in a New GEOS Simulation", "description": "96 chemical species are shown from a GEOS atmospheric simulation || gmao_chem_3x3_pass02_09.05630_no_overlay_print.jpg (1024x576) [126.9 KB] || gmao_chem_3x3_pass02_09.05630_no_overlay.png (5760x3240) [2.5 MB] || gmao_chem_3x3_pass02_09.05630_no_overlay_searchweb.png (320x180) [82.3 KB] || gmao_chem_3x3_pass02_09.05630_no_overlay_thm.png (80x40) [6.8 KB] || 1920x1080_16x9_p30 (1920x1080) [0 Item(s)] || gmao_chem_HD_1080p30.webm (1920x1080) [36.0 MB] || gmao_chem_HD_1080p30.mp4 (1920x1080) [267.3 MB] || 9600x3240_16x9_30p (9600x3240) [0 Item(s)] || 3840x2160_16x9_p30 (3840x2160) [0 Item(s)] || gmao_chem_5x3_preview.mp4 (3200x1080) [429.0 MB] || gmao_chem_4k_2160p30.mp4 (3840x2160) [762.1 MB] || gmao_chem_HD_1080p30.mp4.hwshow [212 bytes] || ", "hits": 188 }, { "id": 14190, "url": "https://svs.gsfc.nasa.gov/14190/", "result_type": "Produced Video", "release_date": "2019-11-07T00:00:00-05:00", "title": "NASA Explorers | Season Three: Fires", "description": "Complete transcript available. || S3_Trailer_Thumbnail.png (2136x1102) [999.3 KB] || S3_Trailer_V2.mov (3840x2160) [2.8 GB] || S3_Trailer_V2.mp4 (3840x2160) [44.3 MB] || S3_Trailer_V2.webm (3840x2160) [9.7 MB] || S3_Trailer_Captions.en_US.srt [846 bytes] || S3_Trailer_Captions.en_US.vtt [858 bytes] || ", "hits": 20 }, { "id": 13126, "url": "https://svs.gsfc.nasa.gov/13126/", "result_type": "Produced Video", "release_date": "2019-07-01T12:00:00-04:00", "title": "Predicting Landslides", "description": "When the rain falls, the land slides. || ClimatologyJanuary_Cover_16x9.png (1280x720) [966.0 KB] || ClimatologyJanuary_Cover_16x9_1024x576.jpg (1024x576) [96.2 KB] || ClimatologyJanuary_Cover_16x9_1024x576_print.jpg (1024x576) [57.3 KB] || ClimatologyJanuary_Cover_16x9_1024x576_thm.png (80x40) [4.4 KB] || ClimatologyJanuary_Cover_16x9_1024x576_searchweb.png (320x180) [53.8 KB] || ", "hits": 221 }, { "id": 13198, "url": "https://svs.gsfc.nasa.gov/13198/", "result_type": "Produced Video", "release_date": "2019-05-01T13:00:00-04:00", "title": "Human Influence on Global Droughts Goes Back 100 Years", "description": "Music: In Light of Things by Matthew Charles Gilbert DavidsonComplete transcript available. || Hydroclimate_Thumbnail.png (1920x1080) [3.1 MB] || Hydroclimate_Thumbnail_print.jpg (1024x576) [166.5 KB] || Hydroclimate_Thumbnail_searchweb.png (320x180) [114.8 KB] || Hydroclimate_Thumbnail_thm.png (80x40) [7.6 KB] || Hydroclimate_highres.mp4 (1920x1080) [330.6 MB] || Hydroclimate_V4.en_US.srt [1.8 KB] || Hydroclimate_V4.en_US.vtt [1.8 KB] || Hydroclimate.webm [0 bytes] || Hydroclimate.mov (1920x1080) [2.5 GB] || ", "hits": 256 }, { "id": 4464, "url": "https://svs.gsfc.nasa.gov/4464/", "result_type": "Visualization", "release_date": "2018-12-14T00:00:00-05:00", "title": "Using Tree Rings to Study Human Influence on Hydroclimate", "description": "This visualization displays a global drought atlas dating back to 1400, created using data from tree rings.

As El Niño changed global weather patterns Southern Africa went into severe drought. On top of already dry conditions, the region experienced its lowest rainfall in 35 years.With the Soil Moisture Active Passive (SMAP) mission, launched in 2015, NASA has dedicated soil moisture measurements for the first time – and could see this severe drought emerging. SMAP's highly sensitive microwave radiometer detects the energy emitted by soil depending on how wet or how dry it is. The old gardener's trick is to squeeze a handful of dirt in your hand and see whether it clumps or falls apart. Think of SMAP doing the same thing – with a lot more precision, all around the world, every 3 days.SMAP allowed us to see a connection between Pacific Ocean water temperatures and the moisture of the soil in Southern Africa. These measurements are now being put to operational use more than ever. SMAP's data was fed into the USDA's global crop yield forecasts – the Foreign Agriculture Service reports that help drive multi-billion dollar commodity markets around the world. In fact, the Foreign Ag Service scientist for this region said that with SMAP they now have the first reliable soil moisture data in 30 years.As crops failed and soils were left bare, we used the Terra and Aqua satellites to assess these effects on the vegetation from a local to regional scale. The Normalized Differential Vegetation Index (NDVI) reflects the health of vegetation on the land surface.As this drought spread across Southern Africa, nearly 30 million people were at risk of drastic food shortages. Four out of 10 people did not have access to clean drinking water.The analyses and data provided by NASA scientists are also critical to a USAID program called the Famine Early Warning Systems Network. As food crises arise, the global view provided by NASA scientists informs decisions about where governments and relief agencies should send help.In Southern Africa in 2015 and 2016, nearly 350 million dollars of emergency water and food aid were delivered, in part based on NASA data, to aid millions of people.As the peak of the drought hits in January 2016, the animations show the low soil moisture conditions in Zambia, Zimbabwe, and Botswana.

Seasonal occupational movement along rivers and in forested areas increases transmission and concentrates malaria in specific regions. The objective of Malaria Project, an ongoing study led by William Pan and Ben Zaitchik, is to develop a detection and early warning system for malaria risk in the Amazon. Using data from NASA satellites and a Land Data Assimilation System (LDAS), the scientists hope that their research can help health officials pinpoint where to deploy resources and what resources to deploy during a disease outbreak. By incorporating NASA data such as precipitation, soil moisture, air temperature, and humidity into their new system, scientists are better able to predict where malaria-spreading mosquitoes are breeding. These climate factors in conjunction with a population density and human movement model will help scientists better understand where and when people are at high risk for malaria. The malaria warning system will predict outbreaks and simulate response to help a country's health care system to more strategically determine where to deploy their resources. Visualizations focus on Peru, one of the central areas of malaria transmission in the Amazon. Four LDAS data sets -- precipitation, soil moisture, air temperature, and humidity are illustrated below.

It includes a quick start guide for educators and first-hand stories (blogs) for learners of all ages by NASA visualizers, scientists and educators.

Read all the blogs and find educational resources for all ages at: the Earth Science Week 2015 page.You are the Project Scientist and Education and Public Outreach (EPO) lead for the Rad-X Project. What is Rad-X, why is it important, and what is the EPO and project scientist's role?NASA's Radiation Dosimetry Experiment, or RaD-X, is a low-cost, high-altitude balloon project. Its mission is to help us understand and quantify cosmic ray exposure at the top of atmosphere. That's the zone where commercial airlines fly. This is important because these cosmic rays are a primary source of ionizing radiation in the atmosphere and increase the risk of cancer and other health impacts. A pilot absorbs as much radiation as a worker in a nuclear power plant, yet the dose of radiation they receive during a cosmic storm or during the span of their career is not quantified or documented.The RaD-X payload consists of four radiation sensors that are used to measure incoming radiation. The RaD-X payload was launched on September 25, 2015 via a high-altitude research balloon. This supplements NASA's Nowcast of Atmospheric Ionizing Radiation for Aviation Safety (NAIRAS) model, which helps us make informed decisions about radiation exposure safety for flight crews, the general public, and commercial space operations. RaD-X also supported Cubes in Space on their inaugural balloon flight, which carried various science projects from schools across the U.S. Cubes in Space is a global design contest in which teams of secondary school students from around the world develop unique science experiments for launch into the upper atmosphere. During the 24-hour mission, the RaD-X payload and Cubes in Space experienced altitudes above 100,000 ft. during the day and above 60,000 ft. during the night. On RaD-X, I had dual roles. First as the Project Scientist it was my job to serve as an interface between the scientists and engineers. Essentially, to help them speak the same language and communicate effectively. I was also the EPO lead. This included coordinating school visits, developing fact sheets, and interfacing with NASA Langley Research Center’s public affairs and communications.How do you use Earth visualizations? Does it have applications to the Rad-X project?Using data from the NAIRAS model, we create visualizations of predicted radiation exposure at multiple altitudes. These show exposure rates at aircraft levels and a vertical profile on global exposure rates. Now that we have successfully launched the Rad-X mission, we have started to analyze real data. During the launch we monitored (in real-time) how the measurements compared with the model predicted values from NAIRAS. Creating visualizations in real-time made the comparisons easier to interpret. || ", "hits": 12 }, { "id": 11923, "url": "https://svs.gsfc.nasa.gov/11923/", "result_type": "Produced Video", "release_date": "2015-08-18T11:00:00-04:00", "title": "Drifting Through Space", "description": "Discover how light from the sun can change the path of an asteroid. || c-1920.jpg (1920x1080) [160.1 KB] || c-1280.jpg (1280x720) [113.0 KB] || c-1024.jpg (1024x576) [82.2 KB] || c-1024_print.jpg (1024x576) [85.0 KB] || c-1024_searchweb.png (320x180) [51.9 KB] || c-1024_web.png (320x180) [51.9 KB] || c-1024_thm.png (80x40) [10.2 KB] || ", "hits": 80 }, { "id": 11964, "url": "https://svs.gsfc.nasa.gov/11964/", "result_type": "Produced Video", "release_date": "2015-07-29T10:00:00-04:00", "title": "How Sunlight Pushes Asteroids", "description": "Rotating asteroids have a tough time sticking to their orbits.

While the Atlantic hurricane season was remarkably quiet and mostly uneventful, the typhoon season was active and intense in the Western Pacific Ocean, though not necessarily out of character for the region.2013 Atlantic Hurricane SeasonThis map shows the tracks and intensity of the tropical storms in the Atlantic basin in 2013. The color and width of each line reflects the intensity of the storm on each day of its activity.In the Atlantic, 13 tropical storms were observed (plus one tropical depression), with just two developing into hurricanes—the fewest since 1982. None of the storms became major hurricanes, the first time that has happened since 1994. The U.S. National Weather Service ranked 2013 as “the sixth-least-active Atlantic hurricane season since 1950.”“This unexpectedly low activity is linked to an unpredictable atmospheric pattern that prevented the growth of storms by producing exceptionally dry, sinking air, and strong vertical wind shear in much of the main hurricane formation region,” said Gerry Bell, lead seasonal hurricane forecaster at NOAA’s Climate Prediction Center. “Also detrimental were several strong outbreaks of dry and stable air that originated over Africa.”2013 Western Pacific Typhoon SeasonThis map shows the tracks and intensity of the tropical storms in the Western Pacific basin in 2013. The color and width of each line reflects the intensity of the storm on each day of its activity. In 2013, there were between 28 and 31 tropical storms, and 13 to 16 typhoons—six of which reached super typhoon strength. According to the Tropical Storm Risk Consortium, the average is 26 tropical storms and 16 typhoons; other institutions have arrived at slightly different counts for the region.Nearly one-third of the world’s tropical storms form in the Western Pacific in any given year. This is because the sea surface temperatures are among the warmest in the world; the mixed layer of the ocean is deeper; there are fewer land barriers; and the tropopause—the boundary between the lower atmosphere and the stratosphere—is very high and cold. Essentially, storms have more fuel and more room (horizontally and vertically) to grow in the Western Pacific. || ", "hits": 47 }, { "id": 11377, "url": "https://svs.gsfc.nasa.gov/11377/", "result_type": "Produced Video", "release_date": "2013-11-08T12:00:00-05:00", "title": "Ask A Climate Scientist - Extreme Weather and Global Warming", "description": "Is the frequency of extreme weather events a sign that global warming is gaining pace and exceeding predictions?Bill Patzert, a scientist at NASA's Jet Propulsion Laboratory, says the evidence that extreme weather events have been more frequent in recent years is definitely to the contrary. \"The United States has always had extreme weather.

But when Julie McEnery, the project scientist for NASA's Fermi Gamma-ray Space Telescope, checked her email on March 29, 2012, she found herself facing this precise situation. While Fermi is in fine shape today, continuing its mission to map the highest-energy light in the universe, the story of how it sidestepped a potential disaster offers a glimpse at an underappreciated aspect of managing a space mission: orbital traffic control. As McEnery worked through her inbox, an automatically generated report arrived from NASA's Robotic Conjunction Assessment Risk Analysis (CARA) team based at NASA's Goddard Space Flight Center in Greenbelt, Md. On scanning the document, she discovered that Fermi was just one week away from an unusually close encounter with Cosmos 1805, a dead Cold-War era spy satellite. The two objects, speeding around Earth at thousands of miles an hour in nearly perpendicular orbits, were expected to miss each other by a mere 700 feet.Although the forecast indicated a close call, satellite operators have learned the hard way that they can't be too careful. The uncertainties in predicting spacecraft positions a week into the future can be much larger than the distances forecast for their closest approach. With a speed relative to Fermi of 27,000 mph, a direct hit by the 3,100-pound Cosmos 1805 would release as much energy as two and a half tons of high explosives, destroying both spacecraft. The update on Friday, March 30, indicated that the satellites would occupy the same point in space within 30 milliseconds of each other. Fermi would have to move out of the way if the threat failed to recede. Because Fermi's thrusters were designed to de-orbit the satellite at the end of its mission, they had never before been used or tested, adding a new source of anxiety for the team.By Tuesday, April 3, the close approach was certain, and all plans were in place for firing Fermi's thrusters. The maneuver was performed by the spacecraft based on previously developed procedures. Fermi fired all thrusters for one second and was back doing science within the hour.Watch this video on YouTube. || ", "hits": 45 }, { "id": 4044, "url": "https://svs.gsfc.nasa.gov/4044/", "result_type": "Visualization", "release_date": "2013-02-27T00:00:00-05:00", "title": "The Distributed Water Balance of the Nile Basin", "description": "This visualization shows how satellite data and NASA models are being applied to study the hydrology of the Nile basin. The Tropical Rainfall Measurement Mission (TRMM) Multisensor Precipitation Analysis (TMPA) provides three-hourly estimates of rainfall rate across much of the globe. Here we see the seasonal cycle of monthly precipitation derived from TMPA for Africa, including the Nile Basin. The annual migration of the Intertropical Convergence Zone (ITCZ) from the Nile Equatorial Lakes region around Lake Victoria, source of the White Nile, northward into Sudan and the highlands of Ethiopia, headwaters of the Blue Nile, and back is evident in the seasonal cycle in precipitation. This precipitation cycle drives flow through the Nile River system. The Nile basin, however, is intensely evaporative, and the majority of the water that falls as rain leaves the basin as evaporation rather than river flow—either from the humid headwaters regions or from large reservoirs and irrigation developments in Egypt and Sudan. The Atmosphere Land Exchange Inverse (ALEXI) evapotranspiration product, developed by USDA scientists, uses satellite data to map daily evapotranspiration across the entire Nile basin, providing unprecedented information on water consumption. The balance of rainfall and evapotranspiration can be seen in seasonal patterns of soil moisture, as simulated by the NASA Nile Land Data Assimilation System (LDAS), which merges satellite information with a physically-based land surface model to simulate variability in soil moisture—a critical variable for rainfed agriculture and natural ecosystems. Finally, the twin satellites of the Gravity Recovery and Climate Experiment (GRACE) can be used to monitor variability in total water storage, including surface water, soil moisture, and groundwater. The annual cycle in GRACE estimates of water storage anomalies clearly shows the seasonal movement of water storage due to precipitation patterns and the movement of surface waters from headwaters regions into the wetlands of South Sudan and the reservoirs of the lower Nile basin.The Nile is the longest river in the world and its basin is shared by 11 countries. Reliable, spatially distributed estimates of hydrologic storage and fluxes can provide critical information for water managers contending with multiple resource demands, a variable and changing climate, and the risk of damaging floods and droughts. NASA observations and modeling systems offer unique capabilities to meet these information needs. || ", "hits": 88 }, { "id": 10764, "url": "https://svs.gsfc.nasa.gov/10764/", "result_type": "Produced Video", "release_date": "2011-05-02T12:00:00-04:00", "title": "India's Disappearing Water", "description": "During the past decade, groundwater beneath the northern Indian states of Punjab, Haryana, and Rajasthan has decreased by more than 88 million acre-feet.

Now at risk of experiencing severe shortages of this vital resource are the 120 million inhabitants of those regions. Using NASA's twin GRACE (Gravity Recovery and Climate Experiment) satellites, scientists measured tiny shifts in the Earth's gravitational field to determine the rate of groundwater change in India. Areas in red had slightly less mass due to a net loss of groundwater and therefore exhibited a weaker gravitational pull on the orbiting satellites.
